A component for an electrochemical cell is formed by additive manufacturing process. The additive manufacturing process can be repeated to produce fuel cell stack.

Method of making components for an electrochemical cell and an electrochemical cell and cell stack

A humidifier for a fuel cell system comprises a stack of thin plates having planar sealing surfaces at their edges. A water permeable membrane is provided between each pair of plates. Each plate defines a gas flow passage along its top and bottom surfaces, with an inlet and outlet defined along edges of the plate, and a flow field extending between the inlet and outlet openings. Inlet and outlet passages connect the inlet and outlet openings to the flow field, and the planar sealing surfaces on both sides of the plate include bridging portions which extend across the inlet and outlet passages. Support structures are provided throughout the flow field and the inlet and outlet passages to support the membrane and diffusion medium layer(s). The support structures may optionally be connected together by webs having holes for flow distribution between the top and bottom of each plate.

Humidifier for fuel cell systems

A method of welding two workpieces together is described. A conductor in electrical communication with a pulse circuit is provided. A portion of the second workpiece is located adjacent the conductor. The two workpieces are also located together. A portion, or all, of one workpiece is welded to the other by applying a pulse current to one of the workpieces. A method of forming a workpiece is disclosed using a pulse current to move the workpiece into a desired shape.
